Greetings,
I currently have a md raid6 reshape (growth, adding a disk) under-way.
Dmesg is beginning to fill up with:
[23661.913556] ata15.00: status: { DRDY }
[23661.914443] ata15.00: failed command: WRITE FPDMA QUEUED
[23661.915326] ata15.00: cmd 61/80:f0:00:34:e9/00:00:45:00:00/40 tag 30
ncq 65536 out
[23661.915329] res 40/00:00:00:00:00/00:00:00:00:00/00 Emask
0x4 (timeout)
[23661.917110] ata15.00: status: { DRDY }
[23661.917977] ata15: hard resetting link
[23664.116087] ata15: SATA link up 3.0 Gbps (SStatus 123 SControl 0)
[23664.118667] ata15.00: configured for UDMA/100
[23664.118685] ata15.00: device reported invalid CHS sector 0
What's the best way to identify ata15.00 and is it permissible to
manually fail this device, without damaging and/or interrupting the
reshape?
I'm also perfectly OK with waiting for it to complete on it's own,
although the speed of the reshape operation has diminished, by my
estimate, about 25% since beginning.
Also, any conjecture on what might lead to the above error(s)?
Thank you very much.
Best,
-EJ
